回答如下:
本句中没有从句。根据句子结构,本句是简单句,不是复合句。本句中的It是形式主语,真正的主语是不定式复合短语for sb to do sth。其中的sb是后面不定式的逻辑主语。不定式复合短语for +宾语+ 不定式在句中可以作主语、宾语、表语、定语和目的状语。例如:
For him to live here is unfit. (= It(形式主语) is unfit for him to live here (真正的或逻辑主语).
The question is for you to answer(表语).
The question for you to answer(定语) is very easy.
I think it (形式宾语)necessary for us to give up this plan (真正的或逻辑宾语).
We must hand in our homework in time for the teacher to correct it(目的状语).
